The Journal of Biosciences is the only 'high impact' journal of life sciences published from India under the aegis of the Indian Academy of Sciences. The journal has established an impressive rapport among life sciences communities in India and elsewhere. Sadly, however, it was flagged recently in a meeting (read ahead) that not many of its well-wishers themselves consider to publish their best of the best research in J Biosci. I attended the meeting of the Editors of the J Biosci recently wherein all interested to the cause of the journal were invited. I found morale of the associates of the journal and the authors quite upbeat, also in the aftermath of recently released 'journal impact factors' – JIF 2008; the J Biosci has recorded a 'comfortable' IF of 1.7! However, I think they need to be careful on the statistics part because the number of papers published by the journal has been traditionally very low; it published about 70 citable articles in a 2 year period. Given this, I thought it will not be appropriate to celebrate the jacked up IF, but to introspect as to why the acceptance rate is so low (just 7%) and why so many commentaries and secondary content being published and not much original research? I guess the board members, might consider to follow the example of PLoS journals wherein many of the PLoS advocates first published their high quality (the so called 'Nature, Cell, Science, PNAS quality' of stuff??) research in the journals they stood for. Well, this proposition didn't go well – there were arguments in favor and against and the excuses given were vivid. We can understand the hesitation, but as someone said, 'charity begins at home'! Other hindering things could be the extraordinarily long time taken by the journal, as told, for completing the peer review (somewhere near 3-4 months) and for eventual publication after acceptance (2 more months). Keeping aside these deficiencies, I think we are looking at an emerging journal coming up from a developing country domain and I am all in favor of publishing there as long as the journal follows an Open Access policy although Springer has already started selling the contents through paid views/downloads under an agreement with the journal/academy.

Failures of citation based rating - new analysis
"The presented results pertain to what we believe to be the largest and most thorough survey of usage- and citation based measures of scientific impact."
I agree with the above statement and I definitely like this thorough comparison of a large number of "impact measures." The article is also informative and has introduced in detail many methods for evaluation of scientific literature with which I was not familiar.
However, on reading the article, I had the following concerns regarding its reliability:
1) Most of the readers will only read the abstract, especially because the article is full of statistical and technical terms. The conclusion of the abstract is not so informative and poorly represents the insightful discussion at the end of the article.
In particular, I would have preferred a positive than a negative conclusion. I would have preferred a recommendation of which measures correlate better with each of the multiple dimensions of scientific attributes (e.g., quality, prestige, impact, immediacy, etc.) rather than the--rather obsolete--conclusion that JIF is not optimal and should be "used with caution." I have read more than 20 articles and editorials (including those in Science, JBC, JCI, PLoS) written in the past two years and stating that JIF should be used with caution.
2) I agree with the authors that JIF is misused; however, a value cannot be blamed for what it does not stand for. I believe the authors have given more importance to JIF (probably because of its "impact" on the scientific community), and I think that this has affected the objectiveness of the paper.
3) As the authors state in the introduction, until now I'm not sure whether how "scientific impact" is defined. Is it "journal impact", "article impact", or "scientist impact"? And which of these matters more? However, the authors seem to have committed the same unfair comparison that JIF and SJR do: measuring articles, scientists, and even "science" itself by the journals rather than by the articles. Journal-level metrics simply mean that an article is evaluated mostly prior to its publication. Once a scientist "makes it to Science or Nature," he or she celebrates even if the article will never be cited again!
4) Once more I declare my agreement with the authors that JIF is neither the most accurate nor the fairest way to measure scientists, articles, or even journals. However, this "conclusion" is clearly stated in the introduction (quoted below). Why the analysis then?
"The JIF is now commonly used to measure the impact of journals and by extension the impact of the articles they have published, and by even further extension the authors of these articles, their departments, their universities and even entire countries. However, the JIF has a number of undesirable properties which have been extensively discussed in the literature [2], [3], [4], [5], [6]. This had led to a situation in which most experts agree that the JIF is a far from perfect measure of scientific impact but it is still generally used because of the lack of accepted alternative"
5) One final concern/question.
Citation-based metrics take into consideration journals that are technologically behind (for many "non-science-related" reasons, including funding problems, poor management, being published in a developing country, etc.) and thus do not have well established web sites but are still citable and cited. Do the "usage-based metrics" just ignore those journals?

Need for qualitative assessment of biomedical research
Here comes a new PLoS ONE article describing one of the most authoritative analyses of the research impact - by none other than the Wellcome Trust. The research conducted by experts of the Trust summates that authoritative opinions about a published research finding constitute important benchmark of the quality of biomedical research. These data vindicate stand of the advocates of post publication peer review (and I am one humble volunteer) that modern day qualitative indicators are extremely necessary to judge the impact of biomedical research findings. Not only that this article supports and strengthens cause of the 'Faculty of 1000' but also that of PLoS ONE, although indirectly. The latter is no doubt the most successful forerunner of the idea of post-publication peer review and qualitative assessment while harnessing the web2.0 based semantic tools for such purposes. At this critical juncture, it is time for the concerned institutions to retrospect about their practices of evaluating research productivity of scientists based on bibliometric indices (such as the 'impact factor') alone.
